Thanks in part to the limited storage capacity of SSDs and low-profile computer cases, many modern-day computers built for speed and efficiency don’t have an enormous amount of storage space available. Though speedy, a 256GB SSD, for example, simply does not provide enough space to store your operating system, games, music, videos, and so on.

If your low-profile case has another 2.5-inch tray, you can double up on the SSDs, but that’s still not even one terabyte, and certainly not enough space to house all of your media. If you don’t want to opt for external media because it makes your rig more cumbersome, SanDisk and Diablo Technologies may have a solution: flash memory built onto DIMM sticks that fit right into your motherboard’s RAM slots.

Dubbed the ULLtraDIMM, SanDisk’s new DIMM SSD isn’t an entirely new concept, but is still quite rare. Unlike a traditional stick of volatile RAM, the oddly capitalized ULLtraDIMMs will retain data even after you’ve powered down. Considering their connections, SanDisk’s sticks can boast super low latency speeds to meet the requirements of enterprise applications — a write latency of under five microseconds, and a read latency of just 150 microseconds.

The sticks come in 200GB and 400GB models, and they’re built to last as well, able to deal with 10 full drive writes per day over the course of five years. As the Tech Report points out, that’s seven petabytes of data on the 400GB model.

Of course, if your computer is built into a smaller case to save space, you might not have enough RAM slots to take advantage of the sticks, but RAM slots are usually more abundant than 2.5-inch trays, and it’s easier to consolidate RAM than SSD capacity.

Say your motherboard only has four DIMM slots, and you’re using all of them with 2GB sticks in each adding up to 8GB — you can free up two of those slots by exchanging those four sticks with two 4GB sticks, and it won’t even be expensive. However, say your two 2.5-inch trays only have two 256GB SSDs in them. Consolidating into a 500GB or 1TB SSD will not save you money — especially if you add another SSD into the newly liberated slot. The price has yet to be divulged, but the sticks are being touted as a more cost-effective solution than standard SSDs.

For now, the sticks don’t seem targeted to consumer use — IBM recently announced that it’ll be using this type of memory inside some of its servers. However, the news today is SanDisk is shipping the sticks to select enterprise servers, so that’s just one more step crossed off the list before they can release to us folk with tiny computer cases in need of more storage.
